Unsteady flow computation for hydraulic systems and power plants
Flow instability and associated unsteadiness in bladed and bladeless regions of hydraulic machines
Techniques for mitigating flow instabilities in hydraulic machines
Experimental and numerical modelling and mitigation of rapid transient flows in hydraulic systems
- 1D-3D coupled simulation for complex transient flows
Vibrations and fatigue induced by flow unsteadiness
Experimental and numerical modelling of fluid-structure interaction in hydraulic machines
Cavitation in Hydraulic Machinery and Systems
Numerical simulation of cavitating flows
Experimental techniques for cavitating flows
Cavitation dynamics on steady or moving surfaces
Vortex cavitation development and dynamics
Cavitation erosion modelling
Experiments on cavitation erosion
Special applications of cavitating flows
Program Overview (Draft)
Day 3, Sept 30
Technical Visit: Discover Alpine Hydropower
Join us on Day 3 for an exclusive, guided tour of a local high-head hydropower plant.
Two guided tours options are planned due to constraints regarding the number of people who can be accommodated on-site.
Pre-registration required.
